Abstract: The focus of this PhD thesis was the technological realization of area contacts to molecular monolayers. n particular, the assembly of Metal-Molecule-Metal junctions by means of soft lithography was investigated. The major challenge is the assembly of the top contact without destroying the molecular layer. Here two approaches were pursued to evaluate new routes of sandwiching biomolecular layers between two metal electrodes. For the fundamental investigation of electron transport through a self-assembled monolayer (SAM) a liquid metal was used as the top contact. This technique was combined with planar microelectrodes as well defined electrode size. An array of 64 micro electrodes ($\textit{Multy Electrode Array}, $MEA) realized on silicon chip served as the bottom electrode. Due to its low toxicity eutectic gallium-indium (EGaIn) was selected as the liquid top contact. By coating the electrodes with a SAM prior to the EGaIn deposition. Metal-SAM-Metal junctions were generated. Initially SAMs of alkonethiols were used as model system for the evaluation $\textit{direct tunneling}$ was found to be the dominant charge transport mechanism for these molecules as well. [...]
